Mode Selector Switch
Figure 2
5. DME MODE SELECTOR SWITCH (NAV 1, HOLD, NAV 2) - Selects
DME operating mode as follows:
NAV 1 - Selects DME operation with NO. 1 VHF navigation set; enables
channel selection by NAV 1 frequency selector controls.
HOLD - Selects DME memory circuit; DME remains channeled to station to
which it was last channeled when HOLD was selected and will continue to
display information relative to this channel. Allows both the NAV 1 and
NAV 2 navigation receivers to be set to new operational frequencies without
affecting the previously selected DME operation.
NOTE
In the HOLD mode there is no annunciation of the
VOR/DME station frequency. However, an annunciator
light located above the HOLD position of the selector
illuminates to inform the pilot that the DME is in the
HOLD mode.
NAV 2 - Selects DME operation with NO. 2 VHF navigation set; enables
channel selection by NAV 2 frequency selector controls.
